GAS-CONTROLLER, ELECTRIC TIME-SWITCH, AND OTHER TIMING- DEVICE.

To aZZ 'whom t may concern:

Be it known that we, ALBERT HoRsTMANN, GUs'rAv Orro HENRY HORSTMANN,ERNST HERMANN HonsTMANN, SIDNEY AnoLrH HonsTMANN, and WILLIAM THOMSONEDGAR, subjects of the King of Great Britain and Ireland, and residentsof'Bath, county of Somerset, England, have invented certain new anduseful Improvements in Gas-Controllers, Electric Time-Switches, andother Timing Devices, of which the following is a specification.

The present invention relates to certain new and useful improvements intime switches'of that type which are actuated by' clock work or the likeand serve to open and close a switch or cock at predetermined referencetimes.

The object of the invention is the provision of a device ofthischaracter which can be readily mountedin position, which can beaccurately and quickly yadjusted to open and close a switch or cock atthe desired times, and which is positive and reliable in its operation.

Wit-h these and other objects in view, the invention consists in certainnovel combinations and arrangements of the parts as will more fullyappear as the description proceeds, the novel features thereof beingpointed out in the appended claims.

For a full understanding of the invention, is-ftofbe had to thefollowing de-V script-ion` and accompanying drawings, in which .f

rels employed in the modilicat-ionillustrated in Fig. 4.

to in the followin description and indicated Corresponding and likeparts are referred in all theviews o the drawings by the vsame referencecharacters.

Referring to Fig. 1 of the drawing, the reference characters a and bindicate two spaced plates having a barrel c arranged between the same,the said barrel being mounted upon a winding arbor @Z which projectsoutwardly beyond the plate a where it terminates in a square headadapted to 'be engaged in the usual manner by a key when winding thespring within the barrel c. The barrel c is `formed with the usual gearwheel c which constitutes one yof the gears of an ordinary clock workortrain of gears controlled by an escapement, the said wheel beingregulated to make one complete revolution every .twenty-four hours orother predetermined period of time. It will also be observed that thebarrel c is formed with a centrally disposed bosse which surrounds thewinding 'arbor and is formed with a bearing e fitting within the openingwithin the plate a; The outer end of the boss is reduced as indicated ate2 and fric upon switch or cock as-may be desired. The in vner end ofeach of the discharge arms Z2 is formed with a disk Z havingia centralopening Z3 therein to receive aboss m which projects outwardly from thedial plate. Dis'hed spring washers 7', such as areshown in detail inFigs-7 and 7 mayy beinterposed be tween the disks Z of the 'variousdischarge arms, and a clamping member n is employed for forcing thedisks Z against the dial plate to lock the discharge arms rigidly in anadjusted position. This clamping member is shown in detail in Figs. 5and 5, and co1nprises a lever n2 having one end thereof bifurcated asindicated at n', the arms of the 'bifurcation terminating in laterallyofset cam portions n3v which are pivotally connected to opposite sidesof the boss m of the dial plate by suitable members such as the screwsn4.

When the lever n2 is swung outwardly away from the dial plate, thethinner portions of the cam members aaare brought into engagement withthe disks Z of the discharge arms so lasto release the said dischargearms and admit of the said arms being turned to any desired positionupon the dial plate. In this position of the locking member fn.,however, the dished spring washers 1' would still frictionally engagethe disks vZ so as to take up any looseness and hold the discharge armsagainst accidental displacement. When the lever n2 is swung inwardlytoward the dial plate g, the

,thicker portions of the cam members ai* are brought into engagementwith the disks Z of the discharge arms so as to force the said diskstightly against the dial plate and hold the discharge arms securely inan adjusted position. Attention may also be directed to the fact thatthe cam portions n of the locking member are formed with the wings a5which project radially from the winding arbor b and are arranged in aplane at right i angles lto the face ofthe dial plate when the upon thesingle arbor da, the said barrels belockingl member is in operativeposition. These wings n.5 are for convenience in setting the time dial gin relation to the exterior index-hand c.

In the operation of the device, the clock work mechanism will cause thedial plate g to make one revolution in every twentyfour hours or otherpredetermined period of time, and as the outer ends Z4 of thedis-`charge levers Zzvcome successively into contact with the switchactuating members arranged in the path thereof, the switch or cock maybe opened and' closed at certain times determined by the position of thedischarge arms with relation to the dial.

A slight modification is shown in Fig. 2 in which the outer reduced ende2 of the boss e projecting from the barrel c is en- ,ga-ged4 by a splitsleeve 7'2 projecting rearwardly from a dial plate h, which carries thedischarge arms (not shown).

A vfurther modification is shown in Fig. 4' in which the clock workmechanism isl formed with a series 'of barrels mounted ing designatedbythe characters c, c3, c4, and c5. The usual springs would be arrangedwithin these barrels, the inner end of each of the springs being,secured to a hook 'e4 upon the boss of the adjacent barrel, while theouter end is secured-to the periphery of the barrel. With thisconstruction, it will be apparent that by applying the key to the varmprojecting arbor the various springs can be wound up 1n the usual mannerso as to admlt of the clock work running for a much longer time thanwould be possible where only one -sprmg was employed.

Having thus described the invention, what we claim as new and desire tosecureby Letters Patent, is I l. A switch actuating deviceincluding adial plate provided upon one side thereof with an axially projectingsleeve adapted to frictionally engage a rotary member to support thedial plate in position, a discharging arm carried by the dial plate, acam for locking the arm to the dial,.and dial setting means carried bythe cam.
